La necesidad de combatir las plagas que afectan a las cosechas y a los animales, ha permitido el desarrollo de los plaguicidas químicos. Los residuos de plaguicidas pueden ser adecuadamente gestionados si se tiene en cuenta su Ciclo de Vida. En el presente artículo se muestran sugerencias para la gestión integrada de este tipo de residuos.

Hazardous wastes include those materials due to their corrosive, reactive, explosive, toxic, flammable or biohazard characteristics, pose a risk to human health and the environment when handled improperly. The type of treatment depends on the characteristics of the waste. The most commonly used treatments are physical, chemical. biological and thermal. Treatment processes also generate waste, which must be deposited in a special landfill or security deposit.

The present article analyzes the role of technology in relation to the economic development and the environment. for the case of developing countries. One considers the adoption of "adequate technology", that is the most advisable technology for a poor country, which must be the result of an ample analysis and discussion by all the sectors involved in the decision making and must comprise of the Plan of Sustainable Development of each country. The adoption of this type of technology will enable the creation of jobs, the protection of the environment, the international trade and the economic development.

The used lubricating oils are wastes of post consumption that require an integral management, for which is necessary that the operators have a set of simple, fast, economic and reliable methods that allow them to characterize oils used for their later advantage. The methods that appear are: water content, (in qualitative form and quantitative form), density and determination of the state of additives (dispersing) or «spot test».

The suitable management and handling of the chemical wastes origínatíng from laboratories allow the saving of reagents and materíals; as well as the reductíon of costs assocíated wíth their handling and final disposal. lt also prevents detriment to the health of the people who have to conduct an academic activity in the laboratory (professors, assistants and students) ora professíonal activity related to service consulting dealíng with chemical analyses (analysts, assistants and auxiliary personnel). The responsible handling of chemícal wastes wíll reduce present and future threats to the health and the environment; as well as the deterioration of materials. Therefore, a method far envíronmental chemical waste management of laboratories is presented.

The necessity to light the plagues that affect to the harvests and the animals, has allowed the development of the chemical pesticidas. The wastes of pesticidas can suitably be managed if its Lile Cycle considers. In the present article are suggestions for the integrated management of this type of wastes.

Los aceites lubricantes usados son residuos de post consumo que requieren una gestión integral, para ello es necesario que los operadores tengan un conjunto de métodos sencillos, rápidos, económicos y confiables que les permitan caracterizar los aceites usados para su posterior reaprovechamiento. Los métodos que se presentan son: contenido de agua, (en forma cualitativa y en forma cuantitativa), densidad y determinación del estado de los aditivos (dispersante) o «spot test».
