3-MCPD (3-monochloropropane-1,2-diol or 3-chloropropane-1,2-diol) is an organic chemical compound with the formula HOCH 2 CH(OH)CH 2 Cl. It is a colorless liquid. The compound has attracted notoreity as the most common member of chemical food contaminants known as chloropropanols. [1] It is suspected to be carcinogenic in humans. [2]
A food web model is a network of food chains. Each food chain starts with a primary producer or autotroph, an organism, such as an alga or a plant, which is able to manufacture its own food. Next in the chain is an organism that feeds on the primary producer, and the chain continues in this way as a string of successive predators.
2-MCPD (2-chloropropane-1,3-diol) is an organic chemical compound with the formula ClCH(CH 2 (OH)) 2. It is a colorless liquid. The compound has attracted notoreity as a food contaminant. Together with the 3-MCPD, it is one of two chloropropanols food contaminants. [1] It is suspected to be carcinogenic in humans. [2]
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Chloropropanols are chlorohydrins related to propanols containing chloride functional group. Eight isomers are possible. Two of these derivatives, 1,3-dichloropropanol (1,3-DCP) and 3-chloropropane-1,2-diol (3-MCPD), are carcinogenic contaminants in processed foods.
The offshore is divided into two further zones, an open water zone and a deep water zone. In the open water zone (or photic zone) sunlight supports photosynthetic algae and the species that feed upon them. In the deep water zone, sunlight is not available and the food web is based on detritus entering from the littoral and photic zones.
A community matrix model is a type of interaction web that uses differential equations to describe every link in the topological web. Using Lotka–Volterra equations, that describe predator-prey interactions, and food web energetics data such as biomass and feeding rate, the strength of interactions between groups is calculated.
