Study Notes
Environmental Chemical Pollution
- Anthropogenic (man-made) substance production is over 500 million tons/year, compared to 5 million tons/year 50 years ago.
- Over 100,000 synthetic chemicals are used in everyday products (e.g., solvents, detergents, dyes, hormones, antibiotics, surfactants, pesticides, mineral oil products).
- Global annual petroleum production is about 3 billion tonnes, with some released through accidents and leaks.
- Over 300 man-made chemicals are found in the bloodstreams of all tested people globally.
Impact of Chemicals on Nature and Human Body
- Air Pollution and Climate:
- Ozone Depletion
- Photochemical Smog
- Acid Rain
- Greenhouse Gases
- Global Warming and Dimming
- Liquid and Solid Pollutants (Land and Water Pollution):
- Polymers and Plastic Pollution
- Toxic Metals
- Organic Anthropogenic Chemicals
- Endocrine Disrupting Chemicals (EDCs):
- Chemicals that interfere with the endocrine system, causing various health problems in mammals.
Key Terms in Pollution
- Persistent Pollutant: Resistant to degradation through chemical, biological, or photolytic processes.
- Bioaccumulation: An organism absorbs a toxic substance faster than it's lost.
- Biomagnification: Persistent pollutant concentration increases as it moves up the food chain.
- Global Distillation: Persistent organic pollutants (POPs) are transported from warmer to colder regions of Earth.
Natural Elemental Cycles
- Biogeochemical cycles involve the movement of atoms between living and non-living environments.
- Examples include the carbon cycle and the phosphorus cycle.
- Human activities significantly impact biogeochemical cycles, particularly with the use of fertilizers.
Fertilizer Drawbacks
- Promote harmful insect growth.
- Shorten and weaken plant roots.
- Cause nitrate accumulation in plants, forming nitrosamines when consumed with meat.
Global Nitrogen Fertilizer Use
- Approximately 100 million tonnes annually since 2010.
- Significant disruption of N and P elemental cycles by human activity, negatively impacting life's future, according to planetary boundaries studies.
Planetary Boundaries Safe Operating Space
- A global framework illustrating the safe operating space boundaries for critical Earth processes.
- In 2023, 6 boundaries were crossed.
Toxic Metal Pollution
- Heavy metals (e.g., Hg, Pb, Cd, Cr, Zn, Cu, Ni, Co, Se) are persistent, typically bioaccumulate and biomagnify in food chains, and have strong EDC properties.
- Examples: lead, mercury, arsenic, cadmium.
- Lead (Pb):
- Globally linked to 600,000 new cases of children with intellectual disabilities annually.
- Exposure from fossil fuel burning, paints, industrial uses, lead pipes, etc.
- Causes neurological impairment, developmental issues, etc.
- Mercury (Hg):
- Released naturally and from anthropogenic sources (coal burning, gold mining).
- Biomethylation converts inorganic Hg to methylmercury (MeHg), a potent neurotoxin.
- Bioaccumulation and biomagnification in food chains.
- Significant health problems if chronically exposed (Minamata disease).
- Arsenic (As):
- Absorbed through GI track and inhalation.
- Linked to skin lesions, neuropathy, gastrointestinal problems, cardiovascular disease, cancer.
- Naturally found in groundwater and crops.
- Cadmium (Cd):
- Highly toxic to kidneys, and can cause various health issues (itai-itai disease)
- Accumulated in liver, kidney, muscle and bone.
- Comes from mining/industrial.
- Aluminum (Al):
- Third most abundant element in the Earth's crust, used extensively in various applications (construction, electronics, packaging).
- Can accumulate in bones, brain, liver, and kidneys.
- Exposure can lead to symptoms similar to Alzheimer's disease in cases of high accumulation.
- Lead (Pb):
Organic Anthropogenic Chemicals
- BTEX Compounds:
- Benzene, toluene, ethylbenzene, xylene.
- Carcinogens found in petroleum products and used in chemical manufacturing.
- Pesticides (Insecticides/Herbicides/Fungicides):
- Organochlorines (DDT, Chlorpyrifos), Organophosphates, Carbamates, Pyrethroids, Sulfonylureas, and Glyphosate.
- Persistent and bioaccumulative; significant impacts on wildlife and human health.
Persistent Organic Pollutants (POPs)
- PCBs (Polychlorinated Biphenyls):
- Widely used in various industrial applications. -Banned and considered highly toxic, and cause various health issues if exposure continues (cancer and developmental problems.)
- Brominated Flame Retardants (BFRs):
- Used in plastics and electronics to prevent fire.
- Bioaccumulate and persistent environmental contaminants, potentially cause various health issues.
- Dioxins: PCDDs, PCDFs:
- Formed during incomplete combustion of organic materials.
- Pose serious human health risks and are linked to cancer, and immune, thyroid, and sexual-development issues.
- Phthalates:
- Used in many consumer products to soften plastics.
- Cause multiple cancers and various other health issues.
- Other Ubiquitous Anthropogenic Chemicals:
-Polyfluorinated organic substances (PFOS)
- Other medicinal chemicals (antibiotics, birth control pills, hormones)
- and their derivatives.
- Other medicinal chemicals (antibiotics, birth control pills, hormones)
