Knowra Environmental chemistry Environmental chemistry Environmental chemistry studies chemical processes in air, water, soil, and living systems, including how substances move, transform, and affect environmental quality.
Biogeochemical cycle : A pathway through which an element or compound moves among organisms, Earth materials, water, and the atmosphere. These cycles describe the natural movement that pollutants can enter or disrupt.
Environmental monitoring : The systematic measurement of environmental conditions and substances over time or across locations. Chemical measurements reveal pollutant levels, trends, and potential exposure.
Chemical equilibrium : A state in which forward and reverse reactions occur at equal rates, leaving concentrations macroscopically stable. Equilibrium predicts how dissolved substances partition among chemical forms.
Minamata disease : A neurological disorder caused by methylmercury exposure, first identified in residents of Minamata, Japan. The disaster showed how aquatic chemistry and food webs can concentrate mercury in people.
Endocrine disruptor : A substance that interferes with hormone signaling in an organism. Environmental exposures raise questions about effects at low doses and during sensitive life stages.
Chemical speciation : The distribution of an element among its chemical forms in a particular system. A pollutant’s form often determines its mobility, toxicity, and availability to organisms.
Analytical chemistry : The branch of chemistry concerned with identifying substances and measuring their amounts. Its methods make trace contaminants measurable in environmental samples.
Acid–base chemistry : The study of proton transfer and the related acidity or basicity of chemical systems. Environmental pH controls solubility, speciation, and reaction rates.
Love Canal : A neighborhood in Niagara Falls, New York, built near a buried chemical-waste site that became a public health crisis. Its contamination brought attention to chemical persistence, migration, and hazardous-waste regulation.
Microplastics : Plastic particles smaller than five millimeters, produced directly or by the breakdown of larger plastics. Their environmental distribution, chemical additives, and biological effects remain active research topics.
