A Catalytic Converter is an Air Pollution Abatement device that removes pollutants from Motor vehicle exhaust, either by oxidizing them into carbon dioxide and water or reducing them

A Catalytic Incinerator is a control device that oxidizes volatile organic compounds (VOCs) by using a Catalyst to promote the combustion process.

Deutsch: Katastrophe / Español: Catástrofe / Português: Catástrofe / Français: Catastrophe / Italiano: Catastrofe

Catastrophe in the environmental context refers to a sudden, large-scale disaster or event that causes significant damage to ecosystems, human settlements, and Natural resources. These events can be natural, such as hurricanes, earthquakes, and floods, or human-induced, such as Oil spills, deforestation, and industrial accidents. Environmental catastrophes often result in widespread destruction, loss of Life, and long-term ecological damage, making them critical issues for global environmental Management and disaster response.

A Categorical Exclusion is a class of actions which either individually or cumulatively would not have a significant effect on the human environment and therefore would not require preparation of an environmental assessment or environmental impact statement under the National Environmental Policy Act (NEPA).

A Categorical Pretreatment Standard is a technology-based Effluent limitation for an industrial facility discharging into a municipal sewer system. Analogous in stringency to Best Availability Technology (BAT) for direct dischargers.

Caterpillar in the environmental context refers to the larval stage of butterflies and moths. These insects play an important role in ecosystems by contributing to plant pollination, serving as a food source for other Wildlife, and impacting plant health through their feeding habits. While caterpillars are an essential part of many food chains, some Species can have significant effects on agriculture and forestry as pests.

A Cathodic Protection is a technique to prevent Corrosion of a metal surface by making it the cathode of an electrochemical

Deutsch: Kation / Español: Catión / Português: Cátion / Français: Cation / Italiano: Catione

A cation in the environmental context refers to a positively charged ion, meaning an atom or molecule that has lost one or more Electrons, resulting in a net positive electrical charge. These positively charged particles are ubiquitous in natural systems, playing fundamental roles in soil chemistry, water quality, nutrient cycling, and the transport of pollutants. Their interaction with negatively charged surfaces, particularly in soil and water bodies, is a critical process known as cation exchange.

A caucus is a meeting of a political party, usually to appoint representatives to party positions.

Deutsch: Ursache / Español: Causa / Português: Causa / Français: Cause / Italiano: Causa /
