Organic Compounds
Molecules primarily made of carbon atoms, which can also contain hydrogen, oxygen, nitrogen, sulfur, and phosphorus.
Inorganic Compounds
Compounds that lack carbon-hydrogen bonds, such as minerals, metals, and water.
Macronutrients
Nutrients required in larger amounts by organisms for growth and survival, such as carbohydrates, proteins, and lipids.
Micronutrients
Nutrients needed in smaller quantities, such as vitamins and minerals, essential for various bodily functions.
Diffusion
The process by which molecules spread from areas of high concentration to areas of low concentration.
Osmosis
A specific type of diffusion focused on water molecules passing through a semi-permeable membrane.
Biomagnification
The increasing concentration of toxic substances within the tissues of organisms at each successive level of the food chain.
Bioaccumulation
The gradual accumulation of substances, such as pesticides, in an organism over time.
Toxicity
The degree to which a substance can harm organisms, often assessed through the concentration of that substance.
PPM (Parts Per Million)
A unit of measurement used to describe very dilute concentrations of substances.
LD50
The lethal dose of a substance that kills 50% of a test population, a common measure of acute toxicity.
Pesticide
Chemicals used to kill pests, including insects, weeds, and fungi.
Biodegradation
The breakdown of organic matter by microorganisms, leading to natural recycling of nutrients.
Acid
A substance that donates protons (H+) in a solution, typically having a pH less than 7.
Base
A substance that accepts protons or donates hydroxide ions in a solution, typically having a pH greater than 7.
pH (pH scale)
A scale used to specify the acidity or basicity of an aqueous solution.
Neutralization
The chemical reaction between an acid and a base to produce a salt and water.
Eutrophication
The enrichment of water bodies with nutrients leading to excessive growth of algae.
Dissolved Oxygen
The amount of oxygen available in water, critical for the survival of aquatic organisms.
Acid Rain
Precipitation that contains acidic components, harmful to ecosystems and buildings.
Effluent
Wastewater or other liquid waste discharged into a natural water body.
Groundwater
Water that fills the cracks and spaces in underground soil and rock layers, a key source of drinking water.
Litmus Paper
A pH indicator paper that turns red in acidic solutions and blue in basic solutions.
Trans Fat
An unhealthy fat created through hydrogenation, which extends shelf life and alters food texture.
Saturated Fat
A type of fat where all carbon atoms are fully bonded to hydrogen atoms, typically solid at room temperature.
Unsaturated Fat
A type of fat with one or more double bonds in its fatty acid chains, typically liquid at room temperature.
Turbidity
A measure of how clear water is, affected by the presence of particles and organisms.
Dissolved Nitrates and Phosphates
Nutrients that can contribute to algal blooms in water systems when present in excessive amounts.
Remediation
The process of cleaning or restoring contaminated environmental systems.
