Latin-American Pesticide Residue Workshop 2017

Pickering at the LAPRW 2017

This year, David Mazawa and Rebecca Smith traveled to and participated in The 6th Latin-American Pesticide Residue Workshop: Food and Environment (LAPRW 2017), which took place from May 14-17 in San Jose, Costa Rica. The location was perfect for discussing the global impact of environmental residues: Costa Rica protects over a quarter of all its land in national parks, wildlife refuges and reserves. And the country boasts nearly 6% of the entire world’s biodiversity!

Costa Rica is home to Macaws and hundreds of other beautiful birds.

This workshop continued building on the success of the previous five LAPRW workshops by keeping scientists and regulators informed about the advances in pesticide residue regulation in food and the environment, methodologies of analysis, instrumentation, risk analysis, monitoring, and quality control assurance of laboratories.

Pickering Laboratories, Inc. is proud to sponsor and support this great conference. We would like to thank the organizers: Centro de Investigación en Contaminación Ambiental (CICA) and different units of the Universidad de Costa Rica (UCR) and the Servicio Fitosanitario del Estado (SFE) of the Ministerio de Agricultura y Ganadería de Costa Rica (MAG). Their hard work and dedication really showed in the quality of the conference and this workshop wouldn’t have been possible without them.

After an exciting week of technical talks and networking with scientists from around the world, we came back to the lab with great contacts, and several new ideas for how to best serve our international customers.

We look forward the next LAPRW workshop at Iguazu Falls, Brazil!

Pickering Attends 4th Annual Latin American Pesticide Residue Workshop

By David Mazawa

The Fourth Latin American Pesticide Residue Workshop (LAPRW) was held from May 26 to 29, 2013 at the Compensar Convention Center in Bogotá, Colombia. About 400 people from universities, private companies, and government agencies responsible for monitoring and regulating pesticide residues in agricultural and environmental samples attended the valuable presentations, discussions, and workshops.Photo May 26, 17 53 47 About 19 different exhibitors, including Pickering Laboratories, proudly sponsored the 4th LAPRW. We would like to thank the Universidad Nacional de Colombia, Sociedad Colombiana de Ciencias Químicas and the Scientific Committee of the Latin American Pesticide Residue Workshop for putting together a great show.

The Latin American Pesticide Residue Workshop (LAPRW) is a biannual open forum for discussion on current concepts and future developments in the field of pesticide residues in food and the environment. Pickering Laboratories was proud to support this workshop by sponsoring and also presenting a poster titled “Glyphosate in soy beans, corn and sunflower seeds by HPLC with post-column Derivatization and fluorescence detection”

The “Pickering Brand”

The “Pickering Brand” is well known all over the world. Thanks to our customers and our dedicated distributers, Pickering Laboratories instruments and methods are utilized in more and more countries. In order for us to offer better service and communication we have been expanding our participation at international meetings.

Pickering Laboratories is regularly represented at the Latin American Pesticide Residue Workshop (LAPRW). The first LAPRW was held in Brazil (2007) and Wendy Rasmussen and I were representing our company. We worked with Roberto de Souza Cruz of Cromatec. The second LAPRW (2009) was in Argentina and David Mazawa and I were representing Pickering Laboratories. We visited our distributer Victorio Bogunovich of Analytical Technologies. We had great cooperation from Analytical Technologies; sharing booth space during the meeting and were able to visit their facility. In Argentina the level of interest and knowledge of participants was much better than the first workshop. At both meetings we had the pleasure to meet lots of interesting people. In Latin America, like other parts of the world many Laboratories are struggling to purchase high performance and high cost instruments. In Argentina during a general discussion, many people expressed their anger about the very high cost of instruments like LC/MS/MS and requested reliable methods with affordable instruments. Latin American countries are using large amounts of glyphosate and are interested in reliable analytical methods in crop and environmental samples. It seems to me that glyphosate is an emotional and political issue in Argentina. The next LAPRW meeting is in Montevideo, Uruguay in 2011.

In 2009, David Mazawa attended BCEIA, China’s largest conference on analytical instruments. David worked with our distributer Ameritech and enjoyed meeting potential customers and as well as their hospitality. You can read more about this trip in our January 2010 Newsletter.

Recently Wendy Rasmussen and David Mazawa represented Pickering Laboratories at Analytica in Germany. Analytica is similar to PITTCON but they meet every second year and it has become larger than PITTCON in recent years. Wendy and David were assisting our distributer and business partner LCTech GmbH during the show. They also received training on LCTech’s new products that we are marketing in the USA.

In April, Wendy and I attended the Western Canada Trace Organic Workshop in Vancouver, Canada. We are presented 2 posters; and Wendy gave a presentation on “Sample Clean-Up with Immunoaffinity columns and Gel Permeation Chromatogphy”. We had a great time and we especially were glad to meet with our distributor, Chromatographic Specialties as well as some current and (hopefully!) future customers. Chromatographic Specialties have a great product range and offer wonderful support all accross Canada.

In June, I will attend the European Pesticide Residue Workshop (EPRW2010) in France. This will be my fourth EPRW meeting. EPRW meets every two years alternating with LAPRW. I will work with our distributor LCTech and visit with our customers. Scientists and pesticide regulators from all over the world will attend this meeting because it is considered by many to be the best pesticide residue workshop. In addition to the Europeans, the attendees are from Africa, Asia, Latin America and North America. This meeting allows me an opportunity to visit with laboratory personnel with different scientific backgrounds, from different parts of the world.

And last but not least, we are regularly participating as exhibiters and presenters at PITTCON and AOAC International. Even though these meetings are in the USA there are lots of foreign scientists attending and this gives us additional opportunity to cultivate our relationship with them.
