Laboratory assessment of environmental impact of phthalazine.

The article presents a study which investigates the environmental effect of phthalazine. The study estimates water solubility, vapor pressure, and Henry's constant using QSAR systems, and the distribution of phthalazine in the environment with the use of Neely 100-day distribution pattern in QSAR system. Results show that phthalazine is classified as slightly toxic to the aquatic organisms, and its toxicity to terrestrial plants is moderate with phytotoxic effects.
