The aim of this study is to examine the role of oxidative stress (OS) by measuring Malondialdehye (MDA) levels to test Lipid Peroxidation as a marker of oxidative stress in serum samples in toxic injuries resulting from exposure to anticholinesterase
insecticides (organophosphates and carbamates) in greenhouse workers in the coastal region of Syria. The study population comprised two groups (the majority of males): greenhouse workers who prepare and spray pesticides (100 workers, aged 18-61) and Control group (not never handle pesticides, 50 subjects, aged 19-58). Malondialdehye (MDA) levels were measured using enzyme-linked immunosorbent assay (ELISA). There was a significant difference in MDA levels in greenhouse workers group compared to control group (P˂0.05). Therefore, MDA levels could be considered as a biomarker for oxidative stress in greenhouse workers exposed to anticholinesterase insecticides and might be a useful diagnostic aid and monitoring exposure in those workers as well as cholinesterase enzyme.

A study of the effectiveness of methyl bromide (MB) and some alternatives
were carried out to determine their effects on soil sterilization, densitY of
nematode and production of tomato (variety Karam) crop, under greenhouses
conditions in Banias
area, during 1999-2000.The treatments were as follows:
MB (57g/m2), Dazomet GR 98%, organic matter + solarization (Biofumigation)
and control. Results showed that the effectiveness in reducing the
total nematode density were 97.5%, 66.1%, 28.8 and 0% respectively. The root
knots index for Meloidogyne spp. were 0, 0.64, 0.83 and 1.83 respectively. The
Bio-fumigation treatment didn't have any effect on reducing the nematode
density, but increased the plant growth and yield. The crop yield were 190.67,
167.33, 185 and 157.67.kg/plot respectively and there was no significant
difference between the MB and the Bio-fumigation treatments.
the residual lead effect in cows milk was
studied in the Governant of Tartous. For this end,135 dairy cows in
different milking seasons and from three different farm stationes
(Zahed cow station,Cement factory farm station and Banias refinery
cow
station) were used.
The objective of the study was to accurately determine lead
concectrations in cows milk in the three different farms. Samples of
milk,soil,water and feedstuff were collected and lead concentration
was determined then statistically analyzed.
