Organochlorine Residues in Marine Organisms

Nature, 1967
Residues of organochlorine insecticides tend to be greater in marine organisms of the higher trophic levels, but the tendency is not found in all food chains. The residues of dieldrin in livers and eggs of adult birds are independent of the age of the bird.

Material Utilization of Organic Residues

Applied Biochemistry and Biotechnology, 2017
Each year, 1.3 billion tons of food waste is generated globally. This waste traces back to industrial and agricultural producers, bakeries, restaurants, and households. Furthermore, lignocellulosic materials, including grass clippings, leaves, bushes, shrubs, and woods, appear in large amounts. Depending on the region, organic waste is either composted,

Process for Disposal of Chlorinated Organic Residues

Journal of the Air Pollution Control Association, 1965
A continuous process for the disposal of halogen-containing organic residues has been developed. This process is based on the decomposition of wastes into gaseous byproducts by high temperature reactions with air and steam. The exit gases, which are essentially carbon dioxide, nitrogen, and hydrogen halides, can be scrubbed with water, thereby ...

Other Organic Residues

2010
Approaches used to analyze the wide variety of archaeological organic residues that do not directly relate to foods are presented in this chapter. The presence and/or distribution of organic compounds that occur in perfumes and cosmetics, beeswax, resins, tar, and pitches and other materials can be used to identify them.

Biodegradation of Organic Residues in Soil

1986
The biodegradation of plant, animal and microbial debris is a complex and multifacited process involving an enormous number and variety of soil organisms. For the purpose of this chapter, biodegradation is seen as involving two distinct yet inter-related phenomena: (1) the breakdown of organic debris and its macromolecular components by extracellular ...

Residues of organic contaminants in beeswax

European Journal of Lipid Science and Technology, 2005
Residues of the varroacides amitraz, chlordimeform, chlorfenvinphos, bromopropylate, coumaphos, tetradifon, acrinathrin, and fluvalinate, the organic microcontaminants 4,4'-DDE, 4,4'-TDE, PCB 153 and PCB 180, and the lipophilic pesticides lindane, chlorpyrifos and endosulfan have been determined by GC/MS in 52 beeswax samples.

Contamination in Organic Residue Analysis

Journal of Eastern Mediterranean Archaeology and Heritage Studies, 2014
ABSTRACTThe excitement of finding ceramic materials on an excavation often leads to questions of function and use that can affect the final interpretation of a site. Organic residue analysis (ORA) is commonly used in determining artifact function. ORA requires collaboration between an archaeologist and chemist in the analysis of the materials. But, the

Analysis of Organic Gunshot Residues

1993
A comparison was made of chromatographic parameters for gas and high performance liquid chromatography methods employed in the analysis of organic gun shot residues. A solid phase extraction procedure was adopted to provide sequential analysis of swabs or filters.

Organic residues in modern agriculture

1986
Manures and composts have been used as a means to increase soil fertility and crop production all along the history of farming. Organic residues were the only means of adding nitrogen and the most important means to add other nutrients until development of chemical fertilizers production and distribution systems.
