In this article, we had studied the touristic site of the Kalamu River in Boma, « Bas-Congo » province in DR Congo. The river had known biophysical changes precisely because of human activities directed toward her. Therefore, these activities have had a negative impact on the smooth running of tourism across the river for nearly 54 years that is why it had been ignored and even forgotten by the people.
Our investigations were based on direct observations, the review of reports and documents of the Boma City office, Agency of Boma National Tourist Office and some research that has been done on this site, and discussion with repentantives of the ONT Agency.
The results obtained show that the river was Kalamu a tourist site visited by various categories of people (fishermen, sailors, officers RVM, population, etc.). It was noticed that the river had lost its normal bed and that during heavy rain, it flooding occurred. The pollution observed introduced the risks of eutrophication of water borne diseases, loss of beautiful scenery, etc. The Baobab site Stanley still remained a special place to visit for tourists of all categories. This publication was done to call the conscience for environmental preservation of the touristic site.

This survey carried out from September 2009 to September 2013 at Maluku, upstream Kinshasa city at the entrance of the Malebo Pool (Congo River, Kinshasa, DR Congo) on three common fish species selected according to their food-chain position. We focused on the contamination in Lead and cadmium of Distichodus fasciolatus (herbivore), Mormyrops anguilloides (carnivore) and Schilbe mistus (carnivore)(Pisces).
We analysed fish heads and flesh according to their size (juveniles and adults). Results revealed that Schilbe mistus was the most contaminated and Distichodus fasciolatus the least contaminated. Adults were more contaminated than juveniles, and heads than flesh. Compared to previous study at Kinsuka, we are proud to conclude that the Congo River ecosystem at Maluku is safe and fish can be eaten without any fear as contaminations are lower than WHO standards.
However, the herbivorous species appeared less contaminated than the secondary and the tertiary species (carnivores and omnivores, respectively).

This paper reports the results of food-chain contamination by the cadmium and the lead, two common heavy metals in the Malebo Pool (Kinshasa) at Kinsuka outlet downstream the Congo River.
The herbivorous species showed lower contamination than carnivores and omnivores, i.e. Distichodus fasciolatus < Mormyrops anguilloides < Schilbe mistus
From each fish sample, heads were more contaminated than in the other edible parts. This allowed us to forbide the consumption of the heads of fish from unkown origins.

This study is related to a cross reading of the legislation governing the waste processing in the Democratic republic of the Congo (DRC), the Cameroon and in Congo-Brazza. It is important to note that one concise inventory of the legal texts reveal that there is an innovation in the taking into account of the question related to the non biodegradable packing in these countries.
Thus, notwithstanding the relevant provisions relating to environmental protection envisaged in the legal and regulatory texts, the African cities in fact the megalopolis of Kinshasa in Congo and that of Yaound

Work accidents and occupational illnesses at RVM Industrial Ecosystem (Boma, D R Congo). This paper reports on work accidents and occupational diseases at RVM/ Boma in D R Congo. Our investigations based on direct observations, literature search and interviewes revealed the effectiveness of such accidents and occupational diseases at RVM industrial ecosystem. This paper is for sensitization and awareness raising within professional ecosystem.
