Types of Water Pollution. Toxic Substance -- A toxic substance is a chemical pollutant that is not a naturally occurring substance in aquatic ecosystems. The greatest contributors to toxic pollution are herbicides, pesticides and industrial compounds.he sources of water pollution are categorized as being a point source or a non-source point of pollution. Point sources of pollution occur when the polluting substance is emitted directly into the waterway. A pipe spewing toxic chemicals directly into a river is an example.
African Cattle. We supply two breeds of cattle from the Horn of Africa: Ethiopian Boran cattle (which have a pronounced hump) and the Somali cattle (which have a smaller hump).
1 Colouration: Just like one of the breeds they have originated from (Angus), most Brangus cattle are black, although there are red Brangus cattle, ass noted below. 2  Some cattle producers may refer Brangus and Red Brangus cattle as collectively Brangus cattle. Body type and characteristics: Brangus cattle are beefy cattle, with the same body characteristics and weight as Red Brangus, Beefmasters and Gerts: moderate-frame, loose skin, more rounded appearance on the rumps, and loose navel in all sexes and ages.
