Following this research we can conclude the following: Valuation results of heavy metals, arsenic, mercury, lead and cadmium in water samples place the coconut there the presence of these metals but does not exceed the maximum permissible limits. Results of the assessment of heavy metals, arsenic, mercury, lead and cadmium in soil samples at the site the coconut there the presence of these metals but does not exceed the maximum permissible limits. Results of the assessment of heavy metals, arsenic, mercury, lead and cadmium in shellfish samples at the site the coconut there the presence of these metals that exceed maximum allowable limits.
