  • Chromium and its negative effects on the environment

    IntroductionTransport of Chromium Into The EnvironmentBioavailabilityImpacts on Human HealthPrevention Or MitigationRelated LinksPhoto CreditsChromium can affect the air quality through coal manufacturing, which eventally can lead to water or soil contamination. Water contamination is fairly limited to surface water, and will not affect groundwater because chromium strongly attaches to soil and is generally contained within the silt layer surrounding or withing the groundwater reservoir. Water contaminated with chromium will not build up in fish when consumed, but will accumulate on the gills, thus, causing negative health effects.
