  • Nickel toxicity in plants: reasons, toxic effects

    Nickel (Ni) is a naturally occurring metal, but anthropogenic activities such as industrialization, use of fertilizers, chemicals, and sewage sludge have increased its concentration in the environment up to undesirable levels. Ni is considered to be essential for plant growth at low concentration; however, Ni pollution is increasing in the environment, and therefore, it is important to

  • Relief systems / vent systems - HSE

    Non-pressurised systems in which fumes and vapours are generated should have adequate ventilation to remove those fumes to a safe place. This may be a scrubber or a stack for discharge. Consideration should also be given to the venting of discharges from relief systems.

  • Single-Acting Hydraulic Cylinders Shipped Worldwide
