None of us are disillusioned enough to think we live in a perfect world. I mean, disease, disorders, and environmental concerns are incredibly prevalent.

And, if you’ve read or heard much about the toxins which seem to now permeate our world, then the above information, albeit brief, comes as no surprise.

The thing is, these contaminants or toxins aren’t just in our soil, water, and air, they’re also in our bodies, accumulating just as they do in wildlife and all throughout our environment.
This is even a growing concern in the coffee industry.

That’s right, there’s few, if any, arenas untouched by the detriments of pollution, chemical-use, industrialization, and non-planet-friendly agricultural practices.

So then, what happens when these toxins compound in our bodies, in the soil, water supply, wildlife, etc.?

Today we’re taking a closer look at bioaccumulation to answer these questions and more, examining the impact toxic build up has on you, the planet, and the coffee industry.

What Is Bioaccumulation, And Why Does It Matter?

To fully understand bioaccumulation, especially as it pertains to the coffee industry, let’s start with the scientific basics. I'm talking full blown scientific terminology…all of it.
Then, we’ll dial it back a bit and seek to break it down and understand how and why this affects each and every one of us before we move on to the impacts this has on one of the world’s most beloved beverages - coffee!

First, the science…

Science Direct, one of the world’s leading platforms for scientific and medical research, defines bioaccumulation as “the net accumulation of all contaminant sources in or on an organism, including water, air, and diet…relative to the environment, bioaccumulation defines the accumulation and enrichment of toxins in organisms.”

Now, let’s unpack the science…

According to this definition, there are indeed things contaminating our planet, things which affect our water, air, and even the items we consume.

And, these contaminants build up or accumulate in these places over time.

To make matters worse, in some cases these toxins interact with or feed on one other, increasing their load and damage to the planet as a whole or to you over time.
And, we weren’t trying to be redundant there, as ‘over time’ is essentially the point of pain for both our planet and our bodies.

In today’s world, it’s hard to escape toxins, no matter whether you’re a plant, an animal, or a human, and this exposure simply compounds, accumulating from a variety of sources until the quality of our air, water, and soil suffers.

Scientists have even found elevated levels of chemicals in animals considered to be at the top of the food chain, suggesting these creatures are exposed to toxins when eating those animals relying more heavily on plant life (which has been contaminated through exposure to pesticides, fungicides, etc.).

As you can imagine, if these things suffer, all plant and animal life suffers, human health declines, and on and on.

So then, what is it exactly that’s contaminating our world so tragically?

In no particular order…

Dioxins - These can be products of natural processes like volcanoes or fires, but most commonly dioxins are present in our air, water, and soil due to industrial incineration.

Unfortunately, animal and human fat and tissue act as a landing point for such toxins, a place where these are stored and accumulate over time, resistant to metabolic breakdown.
Dioxins are highly toxic, linked to many cancers, reproductive and developmental concerns, hormone disruptions, and impaired immune function.

Glyphosate - This globally used herbicide is not said to bioaccumulate within an organism; however, it can accumulate in soil, contaminating crops and the animals eating those crops (including humans).

Glyphosate is also stable in the air, and its widespread, even extensive, use is wreaking havoc on human health, linked to some cancers as well as being a neurotoxin with negative effects on the gut microbiome, liver, kidneys, and reproductive system.

Arsenic - Yes, arsenic is a natural toxin, a heavy metal which can be found in soil and groundwater due to natural processes like erosion. However, industrial emissions and pesticide use is also to blame for this harmful contaminant reaching your body.

As a natural substance, it has been argued that arsenic cannot be entirely removed from our food supply, but it’s important to note arsenic does not break down, meaning habitual pesticide use can cause this toxin to accumulate in large amounts in soil.

Arsenic is associated with skin, lung, and bladder cancer, cardiovascular disease, and more.

Lead - This heavy metal is a neurotoxin which is often present in agricultural fertilizers (amongst other things). When used in agricultural applications, not only are the plants contaminated, but the soil is permanently damaged as this mineral does not break down.

As humans, lead can enter and accumulate in our bodies when we eat foods grown in contaminated soil or those which have been sprayed with chemical pesticides or fertilizers, etc.

Exposure to lead, whether from home sources such as paint, pipes, etc. or from soil or water contamination, can result in behavioral and learning concerns in children; it can also negatively affect blood pressure, memory, etc.

Mercury - Used in pesticides and fungicides for years, mercury has now been banned in many countries; however, like lead and arsenic (as well as cadmium, etc), mercury persists in the soil and in our waterways.

What’s worse, some superphosphates used in fertilizers can contribute to the concentration and accumulation of heavy metals (like mercury) in soil, thereby contaminating foods grown in the soil.

As with the other heavy metals mentioned above, oftentimes agencies deem these as having no risk to the public, but the ability for these to accumulate in our soil or in our bodies should warrant excess caution.

Mercury negatively affects the nervous, immune, and digestive systems, It also causes damage to kidneys and developmental delays in children.

Now, while we’ve briefly touched on the fact that some of these persist for years (or more) in the environment, let’s get a better picture of this before we move on to the impacts such toxins are having on the coffee industry.

There are some natural events or processes which can cause the release, presence, and accumulation of contaminants in our environment.

For instance, some natural disasters contribute to the presence of heavy metals, such as volcanic eruptions.

However, the greatest cause(s) for their presence in the environment and our food comes down to waste disposal methods, industrialization, and the use of chemical pesticides, fungicides, fertilizers, etc. during the growing process for most agricultural crops.

When crops are sprayed, soil, water, and air are compromised, oftentimes for years to come.

These toxins are not only present in the plant itself, leading to contamination when consumed (by pests, predators, and on up the food chain), but they also run off into nearby waterways, contaminating aquatic life then entering the air we breathe as the water cycle simply operates how nature intended - evaporation, condensation, precipitation.

Ultimately, as these toxic substances are present throughout all areas of our environment (soil, air, water), they magnify as they proceed up the food chain.

We’ve touched on this process throughout our discussion thus far, but to elaborate humans and other top predators in the food chain can receive highly toxic doses of these contaminants as they accumulate in the environment in which our food is grown, a process known as biomagnification.

And, some of the most toxic, and abundant, contaminants exist in the chemicals used to spray agricultural crops, including coffee.

Impacts Of Bioaccumulation on the Coffee Industry

The message resting beneath the surface of the material we’ve covered thus far is simple - the health of the earth’s soil, water, and air matters!

Contaminated soil means contaminated food…

Toxic water means toxic food…

Polluted air means polluted food…

…from fruits and vegetables to the animals which rely on these sources for survival, and on and on, contamination at any level affects you, me, and everyone and everything in between - even coffee.

So, let’s take a look at how bioaccumulation is specifically affecting the coffee industry.

Soil Contamination - If coffee shrubs are planted in areas where soil has been compromised through industrialization and agricultural practices, resulting in the presence of heavy metals, pesticides, and other contaminants, these toxins are transmitted to the coffee cherries through the plant’s root system.

This concept is likely self-explanatory.
But, contamination can also occur during processing.

When the outer fruit is removed from the inner seed or coffee bean, this produces a lot of waste (pulp).

Of course, anyone who has a compost bin/pile at home knows organic matter can potentially be beneficial…that is if the coffee cherry pulp is not contaminated in the first place.

When coffee is sprayed with chemical pesticides, fertilizers, etc. this pulp waste is hazardous and toxin-heavy, a by-product which typically ends up in nearby waterways or soil, causing further pollution.

So, from the growing process to the waste created in production, the environment is repeatedly contaminated when conventional growing/processing methods are incorporated.

Pesticides And Other Chemicals - This may seem repetitive at this point, mentioning pesticide, fungicide, herbicide, and fertilizer use in coffee growing practices, but these chemicals, rampant in the conventional coffee industry, make up the largest threat to bioaccumulation as it pertains to this beloved bean.

These harmful chemicals don’t just taint the cup of joe produced directly amidst these practices, they also contaminate the soil, water, and air surrounding coffee plantations for generations to come.

As we mentioned above, these chemicals, including heavy metals and more, remain in the soil.

And, when this conventional coffee growing process has depleted and destroyed the soil thus impacting yield, these companies just pick up, go elsewhere, and start the process all over again.

As you can imagine, such methods are robbing forests, wildlife, and our planet on repeat while contributing greatly to the toxic overload pervading our planet.

Secondary Metabolites - Secondary metabolites are those toxic substances such as mycotoxins like aflatoxins or ochratoxin A, each of which are linked to liver damage, various cancers, gastrointestinal issues, immune dysfunction, neurological disorders, and more.
While these toxins are not sprayed onto the coffee shrubs like pesticides, they do commonly grow in conditions such as those found in coffee growing regions/climates.

Typically, these metabolites are a problem in conventionally grown coffee as the humid environment, at low elevations, and processing practices allow for mold growth.

Then, as the mold feeds on the natural plant matter and grows, it produces metabolites, such as mycotoxins, substances prevalent in coffee which are toxic to humans.

Now For The Good News…

I know, we’ve presented you with a lot of gloom and doom with this topic, but there is some good news to report as well.

First, growing consumer awareness and overall environmental and health concerns are placing pressure on the coffee industry as a whole to…well…get their act together!

Organic and/or sustainable farming practices have not only entered the conversation, but these methods are also being pushed upon industry leaders as ‘the way forward.’

Of course, this doesn’t mean the battle is won.

And, should conventional growing practices, in the coffee industry and beyond, ever truly prioritize health over profit and production, even then, in many areas soil quality has already been compromised for generations.

This is why, for the health of our planet and the health of your body, it’s imperative to choose a coffee that gets it right.

But, what does that look like?

To avoid toxic contamination:

Choose a coffee that’s grown on small farms, with family owners who know and control the planting, growing, and harvesting processes.
Opt for java which is grown amongst native plant and animal life, not hybrid varieties grown in full sun, demanding the deforestation of entire terrains, destroying soil integrity and wildlife habitats for generations.
Choose a coffee committed to sustainability, plants grown without the use of chemicals - no fertilizers, no fungicides, no herbicides, no pesticides…none of it!

Instead, research/find coffee companies which prioritize natural methods of pest control, those which increase the bioavailability of an area by allowing new pollinators, predators, and even prey to inhabit the same ground where the coffee beans grow.

Methods like this enhance the entire growing process, even resulting in a more nutrient dense product as the flora and fauna of the region eat, produce waste, decompose (plant and animal matter), boosting the health of the soil, plants, animals, and ultimately the planet - the way nature intended.

Drink coffee that also prioritizes health throughout processing, omitting any chemicals in this process as well. For example, instead of using machines to harvest coffee, opt for a company that harvests ripe coffee cherries by hand, then using spring water to wash the beans, ensuring no contamination occurs.
Choose a company that backs up these efforts with proof, having each and every batch of coffee beans third-party tested for those toxins, heavy metals, and more that we’ve highlighted today.

In other words…choose Lifeboost Coffee.

Sounds a little self-serving, right?

Perhaps, but this is what we stand on!

Each of the sustainable, toxin-free, environmentally friendly, health conscious aspects of coffee farming we’ve mentioned here are those we fully incorporate and demand as a coffee company.

We can hope and wish larger companies would follow suit for the sake of both planetary and human health, but we can do even more when we lead the way, insisting upon and ensuring our practices set a standard for toxin-free farming and toxin-free sipping!

FAQ

1- Are all organic coffees toxin-free?

Not necessarily.

Unfortunately, organic certification alone doesn’t ensure a lack of heavy metals, etc. as some organic farming allows for organic fertilizers which may still contain heavy metals.

To ensure the coffee you’re sipping is truly clean, look at the company’s growing, harvesting, and processing practices to ensure no chemicals are used at any point in production.
