accident (An unexpected occurrence, failure or loss with the potential for harming human life, property or the environment) 事故
Accident Prevention Advisory Unit 事故预防咨询部
accident source (The cause or origin of an unexpected occurrence, failure or loss with the potential for harming human life, property or the environment) 意外发生源
accidental release of organisms (Genetically engineered organisms that are released in the environment by mistake; once released they may exhibit some previously unknown pathogenicity, might take over from some naturally occurring bacteria (possibly having other positive functions which thus are lost) or pass on some unwanted trait to such indigenous bacteria. There is also concern that an uncontrolled genetic mutation could produce a form with hazardous consequences for the environment) 生物体的意外释放
accounting (Method of recording all the transactions affecting the financial condition of a business or organization) 会计学

acid deposition (A type of pollution which washes out of the atmosphere as dilute sulphuric and nitric acids. It tends to be a regional rather than a global phenomenon, linked to particular industrial activities and meteorological conditions. It includes rain, more than normally acidic snow, mist, sleet, fog, gas and dry particles. It upsets the balance of nature, disrupting ecosystems, and destroys forests and woodlands, plants and crops; kills aquatic life by altering the chemical balance of lakes and rivers and corrodes building materials and fabrics. The pollutants are caused principally by discharges from power station chimneys of sulphur dioxide and nitrogen oxides released by burning fossil fuels, coal and oil) 酸沉积
acid deposition 酸性沉积
acid immissions 酸性注人[污染]物
acid rain (Rain having a pH less than 5.6. The acidity results from chemical reactions occurring when water, sulphur dioxide, and nitrogen oxides, generally released by industrial processes, are chemically transformed into sulphuric and nitric acids) 酸雨
acid-forming gas 形成酸性气体
acidification (Addition of an acid to a solution until the pH falls below 7) 酸化
