- Hits: 283
Works with sensirion-sps Arduino lib (the versions below 1.2.0). Data will be in Serial monitor:
#include <sps30.h>
#include <Wire.h>
// Uncomment for serial plotter format
// #define PLOTTER_FORMAT
void setup() {
int16_t ret;
uint8_t auto_clean_days = 4;
SerialUSB.begin(115200); // Use SerialUSB for MKR boards
while (!SerialUSB) {
; // Wait for USB Serial to be ready
}
delay(2000);
// Initialize I2C on default pins (SDA/SCL on MKR ONE 1310)
Wire.begin();
// Initialize Sensirion I2C layer (usually calls Wire.begin internally)
sensirion_i2c_init();
while (sps30_probe() != 0) {
SerialUSB.println("SPS sensor probing failed");
delay(500);

UN Ocean Gaps, TFA Chemical Risk, €15B Water Investment, EU Microplastics Standard, EV Ship Fire in Pacific

1 — UN Ocean Conference Exposes Gaps in Marine Protection
Only 2.7% of global oceans are fully protected — far short of the 30% by 2030 target.
Officials and researchers called for:
- stricter enforcement of marine pollution rules,
- limits on plastic and chemical pollution,
- better data sharing on marine ecosystem health.
2 — TFA, a New "Forever Chemical," Under EU Review
Trifluoroacetic acid (TFA), a persistent byproduct of PFAS, is now found in rainwater, groundwater, and human breast milk across Europe.
The European Chemicals Agency may soon classify it as a reproductive toxin — a step that would trigger new monitoring and regulation.
3 — €15 Billion EU Investment to Protect Water
The European Investment Bank will invest €15 billion over 3 years in water protection projects, aiming to:
- reduce water pollution,
- improve wastewater treatment,
- cut water waste,
- fund innovation in monitoring and treatment.
4 — First EU Standard for Microplastics Testing
The EU Joint Research Centre (JRC) has released the first reference material for microplastics in water — a PET-based standard for calibration.
This supports the new EU Drinking Water Directive rules requiring microplastics monitoring.
5 — Burning EV Ship in Pacific Raises Pollution Fears
The cargo ship Morning Midas, carrying ~3,000 cars (incl. ~800 EVs), caught fire and was abandoned about 300 miles southwest of Alaska.
Lithium-ion batteries and fuel onboard continue to burn. Salvage efforts are underway.
