Project 8: Action on pesticides
   
 

Southern African Pesticides Newsletter

Newsletter Xhosa version

One of WAHSA's three main sub-projects focuses on Action on Pesticides, is a joint initiative being driven by the Occupational and Environmental Health Research Unit at the University of Cape Town and the Tropical Pesticides Research Institute (TPRI), Arusha, Tanzania.


The main objectives are to

(i) develop improved pesticide safety training and awareness materials appropriate for the region; and
(ii) implement interventions on pesticide use, agricultural policies and pesticide registration in SADC countries; and
(iii) achieve enhanced knowledge and improved surveillance about pesticide exposures and health impacts in the region; and
(iv) develop a strong regional network for information exchange and consultation.


This will be achieved through a range of activities, including:

  • Networking
  • Establishing a Resource Centre at TPRI in Arusha
  • Expanding the electronic Pesticides list server run from UCT
  • Development of joint research protocols on:
  • Surveillance
  • Risk assessment
  • Hazard communication
  • Risk perceptions
  • Safety training effectiveness
  • Economic and health consequences of pesticide use
  • Documenting exposure and health effects from pesticides
  • Development of training materials and a best practice manual
  • Training public officials involved with registration
  • Short course training, and train-the-trainer courses, to practitioners and scientists on pesticides and health
  • Support for formal degree programmes in the SADC region
  • Facilitating exchange visits
  • Supporting a regional situation analysis about occupational health policy and policy on pesticides, and on related research
  • Organisation of a regional conference
  • Action to address exposure in four sites

We would like to invite participation in the activities of the programme, in particular in relation to two of the main activities in the first phase of the project:

a) We aim to establish a network of researchers, service providers and policy makers concerned with pesticide safety, who would assist in the collection and collation of data on pesticide exposures and acute poisoning. We would like to invite recipients of this message to contact the project team to share any information they may have (in the form of published or unpublished reports, theses, papers, descriptions) with the project team on the extent of exposures and poisonings in their countries or locations. These data, often unpublished, may provide very important contributions to establishing an overall picture of the situation with regard to pesticide poisoning in Southern Africa. Through communication of such data, we foresee the development of stronger network in the region committed to health and safety related to pesticides.

b) As part of our action on pesticides, we want to facilitate the development of research activities aimed at
i) the development of improved surveillance for exposures and health impacts in the region;
ii) evaluating and monitoring the effectiveness of hazard communication mechanisms (labelling and safety data sheets) with a view to improving existing measures;
iii) improved understanding of risk perceptions and risk communication amongst target groups dealing with pesticides so as to better inform regional hazard communication strategies; and,
iv) evaluating the effectiveness of different methodologies for training in pesticide safety, particularly involving training in non-chemical or Integrated Pest Management approaches to pest control in the region. To this purpose, we will organize a grant writing workshop for researchers interested in submitting proposals to various funders for activities under the ambit of the WAHSA programme and the Action on Pesticides initiative. The process will involve the submission of draft pre-proposals to an evaluation committee of the programme, who will consider the pre-proposals for appropriateness to the themes of the programme, scientific value and institutional support. Applicants whose pre-proposals are accepted, will be invited to a grant writing workshop to develop proposals for submission to funders.

The South-South meeting on pesticides 2006

Building on a previous South-South meeting on pesticides, WAHSA facilitated a workshop on South-South collaboration on acute pesticide poisoning at the joint SETAC-ANCAP International Conference on Pesticide Use in Developing Countries: Environmental fate, Effects and Public Health Implications, 16th - 20th October 2006, Arusha, Tanzania. The workshop topic was a priority area identified in previous South-South discussions. Without good data on the extent of poisoning, it is difficult to develop appropriate policies on pesticides or to target good prevention strategies at both national and international levels. Through the workshop, we hoped to draw on experiences from developing countries, particularly in Africa and Central America, to develop common tools and approaches which can be used to estimate the extent and nature of the problem in Southern Africa.

WAHSA Pesticide Registrars' Workshop
A workshop of national pesticide registrars from 8 SADC countries was held in Arusha, Tanzania, in October 2006. Issues discussed included the health effects of pesticides, pesticides surveillance, issues in pesticide registration and labelling, and many others. A full report is attached.

The South-south meeting on pesticides

Collaborators from Southern African and South America have developed a network in the field of health effects associated with pesticides use. This report, presented at the International Society of Environmental Epidemiology conference in Johannesburg in September 2005, provides a greater insight into this collaboration.

DNA DAMAGE IN WORKERS OCCUPATIONALLY EXPOSED TO PESTICIDE MIXTURES

Simoniello MF, Kleinsorge EC, Scagnetti JA, Grigolato RA, Poletta GL, Carballo MA.

Cátedra de Toxicología, Farmacología y Bioquímica Legal, Facultad de Bioquímica y Ciencias Biológicas, Universidad Nacional del Litoral, Santa Fe, Argentina. Pesticides are used in agriculture to protect crops but represent at the same time a potential risk to farmers and environment. The aim of this work is the evaluation of 54 subjects occupationally exposed to pesticides and 30 subjects as a control group using the quantification of DNA damage level by means of the alkaline Comet assay and the evaluation of repair processes. Damage index Comet assay (DICA) and damage index repair assay (DIRA) were studied in 27 pesticide applicator workers, 27 non-pesticide applicators and controls. Our results show that both exposed groups revealed significant increase in DICA when compared with controls (P < 0.0001), as well as in DIRA (P < 0.0001). However, the spraying group exhibited a marginally significant difference in DICA (P = 0.05) when years of exposure are considered and a significant difference (P < 0.05) when the personal protective equipment used by individuals was taken as a comparison factor. The influence of confounding factors on the genotoxic effects of occupational exposure to pesticides was investigated and no significant differences were observed considering age, gender, smoking and alcohol consumption in relation to DICA and DIRA. Since DNA damage is an important step in events leading from carcinogen exposure to cancer disease, our study highlights the potential health risk associated with agrochemical exposure in developing countries with vast cultivated areas, such as Argentina.
