POLLUTANTS WHEN PERFORMING LAND MANAGEMENT – STRATEGIES, SAMPLING, ANALYSIS
2
LAND MANAGEMENT VERSUS WATER
Namibia COP11. ExposMeter AB, PhD Per-Anders Bergqvist
Harmful substances usually originate from landWhen changing the use of land, transport of pollutants towater will occur
Water management in not only a question of quantity, m3
The quality of water has to be adressed!
Polluted water has to be treated to proper quality
It means investmentsIn treatment system or else…In treating adverse effects in humansand ecosystem.
Namibia COP11. ExposMeter AB, PhD Per-Anders Bergqvist

MONITORING
• Traditional monitoring shows occurence of specific compounds at few sites (due to expensive sampling)
• BUT• We need to describe all watershed pollution• AND• Identify sources• FOR• Eliminate or reduce effluents and risk
Namibia COP11. ExposMeter AB, PhD Per-Anders Bergqvist
4
ORIGIN OF POLLUTANTS
• Industrial activities• Use of chemicals depending of
the land use• Household activities• Human use• Wastewater treatment plants• Leachate of naturally occurring
chemicals (metals, plant material)
• Leachate from previous land use• Upstream activities
Namibia COP11. ExposMeter AB, PhD Per-Anders Bergqvist
5
INVESTIGATION OF CHEMICALS
• Goal for the investigation• Strategy for investigation• Adjust sampling strategy
due to real field situation – on site• Field sampling• Transport to proper
laboratory• Hi-Tech analysis• Interpretation of results
Namibia COP11. ExposMeter AB, PhD Per-Anders Bergqvist
6
SAMPLING EQUIPMENT
• Integrative sampling• In situ concentration• Non-destructive transport to
proper laboratory
• Need of easy to use, easy to transport, preserving methods.
ExposMeter is the producer of SPMD, POCIS, DGT etc passive
sampling equipment.
Namibia COP11. ExposMeter AB, PhD Per-Anders Bergqvist
7
SAMPLING
• 1-3 weeks absorption in water (TWA concentrations)• In situ preconcentation of up to 200 Liter water• In situ pretreatment for easier analysis• Safe for transport (”no” customs problem)• No degradation or transformation of chemicals
during transport• No need of frozen conditions during transport
Namibia COP11. ExposMeter AB, PhD Per-Anders Bergqvist

TRANSPORT OF SAMPLES
SPMD DGT
• df
POCIS
20 gram 30 gram 10 gram
Namibia COP11. ExposMeter AB, PhD Per-Anders Bergqvist
9
TARGET COMPOUNDS• Industrial chemicals• Pesticides• Combustion created chemicals• Metals• Industrial additives• Food additives• Personal hygiene chemicals• Household chemicals• Medical drugs• Illicit drugs• Veterinary drugs• Environmentally transformed
chemicals• Nutrients, mainly P and N• etc
Namibia COP11. ExposMeter AB, PhD Per-Anders Bergqvist
10
OPPORTUNITIES
• Help industries to describe effluents• Help land management before and after
intervension (positive and negative changes)• Identify sources of pollutants• Regular monitoring to describe temporal and
spacial changes of pollution• To work with sampling even in remote areas
Namibia COP11. ExposMeter AB, PhD Per-Anders Bergqvist
11
EXPOSMETER AB EXPERTISE
• Sampling strategies• Field sampling• Producer of sampling equipment• Access to hi-tech specialised laboratories• Interpretation of analytical results• Quorious, experienced and goal oriented
personnel
Namibia COP11. ExposMeter AB, PhD Per-Anders Bergqvist
12
EXPOSMETER AB LIKE
• To be included in ongoing projects• To act as resource for ongoing project• To participate in planning of projects• To distribute sampling equipment• To teach proper use of passive sampling• To maybe be a open resource to be used by
projects (central sponsored)
