SUMMARY |
Nabam is a toxic fungicide, considered to be a carcinogen and there are some concerns that it may be an endocrine disrupter. It is very soluble in water, hydrolyzes rapidly, rapidly degrades in soil and so leaching to groundwater is unlikely. Its ETU metabolite is an environmental concern. Highly toxic to aquatic organisms. It is not toxic to honeybees. Toxicity data for other species has not been found. |
