Evidence of impacts from DDT in pelican, cormorant, stork, and egret eggs from KwaZulu-Natal, South Africa.

Chemosphere, 2019
DDT remains in use for malaria control in South Africa. We quantified DDTs in aquatic bird eggs from the highly biodiverse northern KwaZulu-Natal, a province of South Africa where DDT has been used for more than 80 years for malaria control. Pelican eggs

DDT: Decoupled Diffusion Transformer

arXiv.org
Diffusion transformers have demonstrated remarkable generation quality, albeit requiring longer training iterations and numerous inference steps. In each denoising step, diffusion transformers encode the noisy inputs to extract the lower-frequency ...

Catalytic hydrotreating of 2,4′-DDT and 4,4′-DDT

Journal of Hazardous Materials, 2004
The results of catalytic hydrotreating of a commercial mixture of 2,4'-DDT and 4,4'-DDT are reported. Experimental runs were carried out in a batch reactor (300 cm3) at constant hydrogen pressure (PH2 = 20 bar) and temperature. Temperature levels 150, 180, 200 and 230 degrees C were tested. A commercial sulphide Ni-Mo catalyst was adopted. The reacting

Evaporation of DDT

Nature, 1971
THE movement of unchanged DDT from treated crops into the atmosphere has been suggested to contribute to the widespread contamination of the environment by this substance1. In field conditions, 50% of DDT applied to the surface of soil has been found to disappear in 16–20 weeks (ref.
