Thus, the aim of the study is to determine the acute toxic effect of oil pollution that may occur as a result of crude oil tanker accidents in the IS. Approximately 50,000 ships pass through the IS each year, with crude oil tankers making up the majority. Environ Toxicol Water Qual 12: 109–115, 1997Ĭountries located on the Black Sea coast perform most of their sea trade through the Istanbul Strait (IS). The episodes of toxicity were greater in the summer months compared to winter months, whereas the pattern of chemical contaminants was not influenced by the seasonal change. The Microtox assay indicated that 31 samples out of 378 samples exerted acute to medium levels of toxicity, which were mostly from sites 6 and 7.
Chemical analysis revealed that the contamination of oil was higher at sites 5 and 6 while four heavy metals were evenly distributed at different sites.
Samples were analyzed for physicochemical characteristics and toxicity using the Microtox assay. To assess the quality of the Shuaiba bay area, water samples were collected twice a week for six months from seven points of discharge, each representing a source from a major industry. What’s included: Quartz cell with cap, power cord, B-heavy oil (standard), 2 amp fuse, 10 mL syringe and 25 µL syringe.Twelve major industries in the Shuaiba Industrial Area of Kuwait generate about 30,000 m3/d wastewater, which is discharged to the sea either directly or after treatment. S-316 solvent can be recycled using Solvent Reclaimer SR-300 (82900-20), sold separately below. Read results on LCD or transfer data using parallel printer port or to computer via RS-232. Use built-in time stamping to document results. Auto-calibrates after initial standard reading. S-316 solvent is non-absorbant at this IR wavelength, so only oil is measured. Analysis is based on infrared (IR) spectral data, with peak integration (at approximately 3.4 µm) to determine oil concentration. The oil / solvent solution is then simply transferred to the OCMA-350 analyzer for single-button measurement. Use S-316 solvent to quantitatively extract sample. Use this precision instrument for surveying water quality and hazardous waste sites, industrial wastewater monitoring, post-cleaning discharge analysis, and measuring adherent oil residuals on textiles and metal parts.
