A gas chromatography mass spectrometry with spike calibration curve method was used to quantify three carbamate pesticides residue in cooked white rice and to estimate the reduction percentage of the cooking process duration. The selected pesticides are three carbamate pesticides including carbaryl and pirimicarb that their MRL is issued by “The Institute of Standards of Iran” and propoxur whic...

abstract soil microbial activity and biochemical processes are often limited by carbon availability in arid- and semi-arid regions, probably due to the low organic matter content. consequently, return of plant residues to soil is a convenient and effortless practice for increasing microbial activities and biochemical reactions. the primary objective of this study was to evaluate the effect of v...

Trametes hirsuta (GenBank Accession Number: AB429065.1), a basidiomycete fungus was used for the production of laccases using different carbon sources namely glucose, sawdust, rice bran and wheat bran. Use of organic medium (agricultural/industrial wastes) is aimed to bring down the cost of media. Among these four carbon sources, the best laccase production was obtained in sawdust followed by w...

After the harvest of crop, disposal rice stubbles remains a notable area interest in all growing areas rice. The present review paper explores and highlights an effective strategy decomposing decomposers paddy stubble. Due to increasing production rice, there is increase crop residues production. Conventional methods management involve burning, surface retention, mulching, bailing, incorporatio...

The residue levels of 16 US EPA priority polycyclic aromatic hydrocarbons (PAHs) and 16 selected organochlorine pesticides (OCPs) in rice and rice hull collected from a typical e-waste recycling area in southeast China were investigated from 2005 to 2007. PAHs and OCPs also were measured in ten mollusk species (soft tissues) collected in an adjacent bay in 2007. Individual PAHs were frequently ...

straw burned (Bird et al., 2001; 2002). Recent work in tropical and temperate rice ecosystems has determined The transition from open-field burning of straw residues to alternathat the operationally-defined mobile humic fraction tive residue management practices may affect soil C sequestration potential and the supply of nutrients to crops. A field study of dual(Na4P2O7 or NaOH extractable) is ...
