ABSTRACT
Em 2004, o Conselho Nacional de Meio Ambiente (CONAMA) aprovou a primeira regulamentação brasileira sobre os procedimentos para avaliação de material oriundo de dragagens: a Resolução CONAMA n° 344/04. Esse ato normativo estabeleceu que, no prazo de cinco anos, contados da data de sua publicação, haveria uma revisão para que fossem estabelecidos os valores orientadores nacionais para a classificação do material dragado. Tal revisão ocorreu, o que culminou na publicação da Resolução CONAMA n° 454/12. Este artigo realiza uma análise comparativa entre a Resolução CONAMA n° 344/04 e a Resolução CONAMA n° 454/12, com o intuito de verificar as principais alterações e acréscimos que foram realizados. Conclui-se que a Resolução CONAMA n° 454/12 não apenas refinou os valores orientadores nacionais para a classificação do material dragado, como também regulamentou aspectos relevantes relacionados ao licenciamento ambiental de dragagens e ao gerenciamento e disposição de material dragado.
In 2004, the National Council for the Environment (Conselho Nacional do Meio Ambiente - CONAMA) approved the first Brazilian regulation on procedures for evaluation of dredged material: CONAMA Resolution No. 344/04. This normative act established that, within five years from the date of its publication, there would be a revision of the national guideline values that were established for the classification of dredged material. This review took place, culminating in the publication of CONAMA Resolution No. 454/12. This article presents a comparative analysis between the CONAMA Resolution No. 344/04 and CONAMA Resolution No. 454/12, in order to check the main changes and additions that were made. We conclude that the CONAMA Resolution No. 454/12 not only refined the national guideline values for the classification of dredged material, but also regulated relevant aspects related to the environmental licensing of dredging activities and to the management and disposal of dredged material.
ABSTRACT
Medical wastes are highly risky as infectious substances or hazardous chemical substances, if out of control, will cause serious environmental pollution and spread of diseases, directly jeopardizing human health. In consideration of such hazards of medical wastes, Chinese laws have made strict regulations on their management, which however fall short in terms of their rigorousness. In the era to build a resource-saving and environment-friendly society, it is imperative to establish and improve an effective mechanism for the regulation of medical wastes, to further improve China's legal system of medical waste management and to upgrade the law enforcement on it.
