Environmental Toxicology: Understanding and Managing Toxic and Hazardous Waste

💡 Toxicology is the study of natural or man-made substances that produce harmful effects on living organisms.

🔬 Toxicity refers to the degree of effectiveness of a poisonous substance in causing harmful effects on health.

🌿 Toxins are naturally produced toxic substances, while toxicants are substances generated by human activities.

🔍 Selective toxicity: Antibiotics kill specific bacteria in the body without harming the whole organism.

🌬️ 🌊 🌱 🍽️ Routes of exposure to toxins: Air, water, soil, and food are common ways toxins can enter the body.

💉 ☠️ ☕ Dose-effect relationship: The amount of a substance that enters the body can have positive or negative effects, such as lethal doses of water or caffeine.

🧬 👤 Individual susceptibility: People can have different reactions to toxins based on their genetic makeup or previous exposure.

👨‍🏫 Toxicology is the study of the effects of toxic substances on living organisms and the environment.

🌎 Environmental toxicology focuses on the impact of chemicals on ecosystems and the environment.

💼 Occupational toxicology is concerned with protecting workers from exposure to toxic substances in their workplace.

📜 Regulatory toxicology establishes safety standards and guidelines for the use of toxic substances.

🍽️ Food toxicology ensures the delivery of safe and edible food to consumers.

⚕️ Clinical toxicology studies the diseases and illnesses related to exposure to toxic substances.

🔬 Descriptive toxicology involves collecting toxicological information through experimentation with animals.

Toxicology can be divided into different types, including regulatory, descriptive, forensic, analytical, and mechanistic toxicology.

Regulatory toxicology sets permissible limits for substances, while descriptive toxicology collects information for research purposes.

Forensic toxicology determines the cause-effect relationship between exposure to a substance and toxic effects or death.

Toxic chemicals can enter the body through plasma membranes, affecting cells at the cellular level.

There are three main types of absorption: passive diffusion, facilitated diffusion, and active transport.

The three main routes of absorption for toxic substances are inhalation, ingestion, and skin contact.

👉 Understanding the digestive system allows for comprehensive analysis of exercise impact and determination of affected areas.

👇 Different substances are absorbed differently based on acidity levels, and understanding absorption pathways is crucial in managing impacts and interactions with the environment.

🌍 Toxic substances can enter the body through inhalation, ingestion, or skin contact, and their distribution depends on factors such as solubility and blood flow.
