HSC Chemistry 2nd Paper Note 5th Chapter Economical Chemistry. Chemical marine pollution can cause many disturbances which, in the shorter or longer term, can have a negative impact on the economy. These effects may be related to living organisms, ecosystems as well as humans and their activities. The methods used to assess economic impact distinguish all that is of commercial value from all that is not. Resources of Resources can easily be calculated as they cover all that can be invoiced.

An example of this is a professional fishing ban due to the intoxication of fish flesh or due to a decrease in tourism in the incident area. Resources of non-commercial value are difficult to calculate as they cover all that cannot be invoiced. Some examples of this are a ban on recreational shellfish collection, sterility in certain mammals or damages caused to protected areas. The other difficulty often encountered when assessing economic impact is the lack of relative data for the reference condition, i.e. before the pollution. For instance, in many countries, there is no water quality control network. The quantity of the substance normally present in the environment is unknown, making it impossible to compare this with the quantity found in the polluted water.

While the assessment of economic impact can prove to be a fastidious task, the question of compensation is a complex issue. Very few compensation systems for chemical pollution currently exist worldwide. Today, there is no worldwide comprehensive mechanism providing for compensation for damage caused that includes the cost of cleaning and restoring the environment. This is why the HNS Convention was created. The types of damages covered are personal injury and/or loss of life, damage to property, economic loss due to HNS pollution, as well as the cost of environmental protection and restoration. All individuals, companies, local and national authorities of a country that has ratified the Convention can claim compensation. In early 2016, the HNS Convention is still not in force.
