About Ohmpa
Asphalt is made from petroleum. Crude petroleum (right out of the ground) contains natural bitumens or asphaltenes, which generally are called asphalt. Asphalt has been used throughout recorded history. [ACS] It is a thermoplastic material (meaning it gets soft when warm), which is recovered from distillation bottoms, sometimes referred to as still bottoms (the gunk left over after crude petroleum has been distilled into gasoline and other useful products).

Describe las propiedades fisicas y quimicas y metodos analiticos de determinacion del di-n-butil-ftalato. Dicho producto es utilizado principalmente como plastificante, lubricante de valvulas de aerosoles, agente antiespumante, alargadores de unas y pulverizadores para el cabello. Identifica las fuentes de exposicion humana y ambiental y describe los mecanismos de transporte, distribucion y transformacion en el medio ambiente. Presenta los efectos en la salud humana y el medio ambiente y plantea recomendaciones para su proteccion
